DETAILED DESCRIPTION OF THE INVENTION Synthesis

The compounds of Formula I can be prepared by contacting an appropriatesulfonyl isocyanate III with and S,S-dialkyl-N-(heterocyclic)sulfilimineII as illustrated in Equation 1. (L, R_(a), R_(b), and A are aspreviously defined.) ##STR8##

The reaction of Equation 1 is best carried out in an inert aproticsolvent, such as methylene chloride, tetrahydrofuran, acetonitrile,ether or chloroform, at temperatures ranging from about -20° to 50° C.In some cases, the desired product may crystallize from the reactionmedium and may be filtered. Reaction products which are soluble in thereaction medium may be isolated by evaporation of the solvent,trituration of the residue with solvents such as diethyl ether, ethylacetate, 1-chlorobutane or hexane. Chromatography (e.g., silica gel) mayalso be necessary for purification.

The sulfonyl isocyanates III used as starting materials are generallyknown in the art and can be prepared by known methods. One methodinvolves reacting an appropriate benzene or heterocyclic sulfonamidewith phosgene in the presence of an alkyl isocyanate, such as n-butylisocyanate, and a tertiary amine catalyst, such as 1,4-diazabicyclo[2.2.2]octane, at reflux in a solvent such as xylene or chlorobenzene.See H. Ulrich and A. A. Y. Sayigh, Newer Methods of Preparative OrganicChemistry, Vol. VI, p. 223-241, Academic Press, New York and London, W.Foerst Ed.

The sulfonyl isocyanates III can also be prepared from sulfonamides by atwo step procedure involving (a) reacting the sulfonamides with an alkylisocyanate in the presence of a base such as K₂ CO₃ at reflux in aninert solvent such as 2-butanone, forming an alkylsulfonylurea, and (b)reacting this compound with phosgene and tertiary amine catalyst atreflux in xylene solvent.

The preparation of sulfonamides from ammonium hydroxide and sulfonylchlorides is widely reported in the literature, e.g. Crossley et al., J.Am. Chem. Soc., 60, 2223 (1938). Certain sulfonyl chlorides are bestprepared by chlorosulfonation of a substituted benzene, naphthalene, orthiophene in carbon tetrachloride according to the teaching of H. T.Clarke et al., Org. Synth. Coll., Vol. 1, 2nd Ed. 1941, p. 85. Othersulfonyl chlorides can be made by diazotization of the appropriate aminewith sodium nitrite in HCl, followed by reaction of the diazonium saltwith sulfur dioxide and cuprous chloride in acetic acid according to theteachings of H. L. Yale and F. Sowinski, J. Org. Chem., 25, 1824 (1960).

The sulfilimine (II) starting materials may be made in a number of ways.S,S-Dimethyl-N-(4,6-di-methylpyrimidin-2-yl)sulfilimine andS,S-dimethyl-N-(4-methylpyrimidin-2-yl)sulfilimine are taught by T. L.Gilchrist, C. J. Harris and C. W. Rees in J.C.S. Chem. Comm., 486(1974). The procedure taught in this article can be adapted to prepareother sulfilimines of Formula II as shown in Equation 2. ##STR9## Aheterocyclic amine IV is contacted successively with tert-butyloxychloride, a dialkylmercaptide and sodium methoxide.

The reaction may be best carried out in an inert aprotic solvent, suchas methylene chloride, chloroform or ethyl acetate at temperaturesbetween -60° to 60° C. for 1-48 hours with ambient pressure. Theresulting solution may be washed with water. In some cases, the desiredproduct may crystallize from the organic solvent and may be filtered.Reaction products which are soluble in the organic solvent may beisolated by evaporation of the solvent after the organic solution isdried over a drying agent such as sodium sulfate or magnesium sulfateand trituration of the residue with solvents such as diethyl ether,1-chlorobutane or hexane. Chromatography (e.g., silica gel) may also benecessary for purification.

Sulfilimines of Formula II can also be prepared by the general procedureillustrated in Equation 3. ##STR10## The appropriate amine IV iscontacted with the appropriate dialkylmercaptide in the presence ofN-chlorosuccinimide.

The reaction is best carried out in an inert aprotic solvent, such asmethylene chloride, chloroform or ethyl acetate at temperatures between-30° to 60° C. for 1-48 hours with ambient pressure. The resultingsolution is then washed with aqueous sodium hydroxide solution and thenwater. The desired product can be isolated as described in the previousparagraph.

Yet another method for preparing the sulfilimines II is shown inEquation 4. ##STR11##

The reaction of Equation 4 may be best carried out in an inert aproticsolvent, such as methylene chloride or chloroform at temperaturesbetween -70° to 70° C. for 1-48 hours with ambient pressure. Theresulting solution may be washed with sodium hydroxide aqueous solutionand then water. The desired product can be isolated as described in theprevious paragraph.

Heterocyclic amines of Formula IV and methods for preparing them areknown in the art. The synthesis of heterocyclic amines such as those ofFormula IV has been reviewed in "The Chemistry of HeterocyclicCompounds", a series published by Interscience Publ., New York andLondon. 2-Aminopyrimidines are described by D. J. Brown in "ThePyrimidines", Vol. XVI of this series. 2-Amino-1,3,5-triazines can beprepared according to methods described by E. M. Smolin and L. Rapaportin "s-Triazines and Derivatives", Vol. XIII of the same series. Thesynthesis of triazines is also described by F. C. Schaefer, U.S. Pat.No. 3,154,547 and by K. R. Huffman and F. C.

Formulations

Useful formulations of the compounds of Formula I can be prepared inconventional ways. They include dusts, granules, pellets, solutions,suspensions, emulsions, wettable powders, emulsifiable concentrates andthe like. Many of these may be applied directly. Sprayable formulationscan be extended in suitable media and used at spray volumes of from afew liters to several hundred liters per hectare. High strengthcompositions are primarily used as intermediates for furtherformulation. The formulations, broadly, contain about 0.1% to 99% byweight of active ingredient(s) and at least one of (a) about 0.1% to 20%surfactant(s) and (b) about 1% to 99.9% solid or liquid inertdiluent(s). More specifically, they will contain these ingredients inthe following approximate proportions:

Lower or higher levels of active ingredient can, of course, be presentdepending on the intended use and the physical properties of thecompound. Higher ratios of surfactant to active ingredient are sometimesdesirable, and are achieved by incorporation into the formulation or bytank mixing.

Typical solid diluents are described in Watkins, et al., "Handbook ofInsecticide Dust Diluents and Carriers", 2nd Ed., Dorland Books,Caldwell, N.J., but other solids, either mined or manufactured, may beused. The more absorptive diluents are preferred for wettable powdersand the denser ones for dusts. Typical liquid diluents and solvents aredescribed in Marsden, "Solvents Guide", 2nd Ed., Interscience, New York,1950. Solubility under 0.1% is preferred for suspension concentrates;solution concentrates are preferably stable against phase separation at0° C. "McCutcheon's Detergents and Emulsifiers Annual", MC PublishingCorp., Ridgewood, N.J., as well as Sisely and Wood, "Encyclopedia ofSurface Active Agents", Chemical Publishing Co., New York, 1964, listsurfactants and recommended uses. All formulations can contain minoramounts of additives to reduce foaming, caking, corrosion,microbiological growth, etc.

The methods of making such compositions are well known. Solutions areprepared by simply mixing the ingredients. Fine solid compositions aremade by blending and, usually, grinding as in a hammer or fluid energymill. Suspensions are prepared by wet milling (see, for example,Littler, U.S. Pat. No. 3,060,084). Granules and pellets may be made byspraying the active material upon preformed granular carriers or byagglomeration techniques. See J. E. Browning, "Agglomeration", ChemicalEngineering, Dec. 4, 1967, pp. 147ff. and "Perry's Chemical Engineer'sHandbook", 5th Ed., McGraw-Hill, New York, 1973, pp. 8-57ff.

Utility

Test results indicate that the compounds of the present invention areactive herbicides. They should have utility for broad-spectrum pre-and/or post-emergence weed control in areas where complete control ofall vegetation is desired, such as around fuel storage tanks, ammunitiondepots, industrial storage areas, parking lots, drive-in theaters,around billboards, highway and railroad structures. Alternatively, thesubject compounds should be useful for the selective pre- orpost-emergence weed control in crops, such as wheat and rice.

The rates of application for the compounds of the invention aredetermined by a number of factors, including their use as selective orgeneral herbicides, the crop species involved, the type of weeds to becontrolled, weather and climate, formulations selected, mode ofapplication, amount of foilage present, etc. In general terms, thesubject compounds should be applied at levels of around 0.05 to 10kg/ha, the lower rates being suggested for use on lighter soils and/orthose having a low organic matter content, for selective weed control orfor situations where only short-term persistance is required.

The compounds of the invention may be used in combination with oneanother or with any other commercial herbicide, examples of which arethose of the triazine, triazole, uracil, urea, amide, diphenylether,carbamate and bipyridylium types.

The herbicidal properties of the subject compounds were discovered in anumber of greenhouse tests. The test procedures and results follow.

Test A

Seeds of crabgrass (Digitaria sp.), barnyard-grass (Echinochloacrusgalli), wild oats (Avena fatua), sicklepod (Cassia obtusifolia),morningglory (Ipomoea sp.), cocklebur (Xanthium sp.), sorghum corn,soybean, rice, wheat, and nutsedge (Cyperus rotundus) tubers wereplanted and treated pre-emergence with the test chemicals dissolved in anonphytotoxic solvent. At the same time, these crop and weed species,along with cotton and bush bean, were treated with a soil/foliageapplication. At the time of treatment, the plants ranged in height from2 to 18 cm. Treated plants and controls were maintained in a greenhousefor sixteen days, after which all species were compared to controls andvisually rated for response to treatment. The ratings, summarized inTable A, are based on a numerical scale extending from 0=no injury, to10=complete kill. The accompanying descriptive symbols have thefollowing meanings:

C=chlorosis/necrosis:

D=defoliation:

E=emergence inhibition:

G=growth retardation:

H=formative effect:

U=unusual pigmentation; and

6Y=abscised buds or flowers.

Several of the compounds of this invention were further tested in apre-emergence herbicide screen as described in Test B.

Test B

Two plastic bulb pans were filled with fertilized and limed Woodstownsandy loam. One pan was planted with corn, sorghum, Kentucky bluegrassand several grass weeds. The other pan was planted with cotton,soybeans, purple nutsedge (Cyperus rotundus), and several broadleafweeds. The following grass and broadleaf weeds were planted: crabgrass(Digitaria sanguinalis), barnyardgrass (Echinochloa crusgalli), wildoats (Avena fatua), johnsongrass (Sorghum halepense), dallisgrass(Paspalum dilatatum), giant foxtail (Setaria faberii), cheatgrass(Bromus secalinus), mustard (Brassica arvensis), cocklebur (Xanthiumpensylvanicum), pigweed (Amaranthus retroflexus), morningglory (Ipomoeahederacea), sicklepod (Cassia obtusifolia), teaweed (Sida spinosa),velvetleaf (Abutilon theophrasti), and jimsonweed (Datura stramonium). A12.5 cm diameter plastic pot was also filled with prepared soil andplanted with rice and wheat. Another 12.5 cm pot was planted with sugarbeets. The above four containers were treated pre-emergence with severaltest compounds within the scope of the invention.

Twenty-eight days after treatment, the plants were evaluated andvisually rated for response to the chemical treatments utilizing therating system described previously for Test A. The data for Compound 1are summarized in Table B. Compound 1 appeared to be one of the mostactive of the compounds tested in this screen; however, the results forthe other compounds tested indicate that they, too, have high herbicidalactivity when applied at low rates as pre-emergence treatments on soil.

A number of compounds were also treated to more accurately define theirutility in post-emergence applications.

Test C

The test chemicals, dissolved in a non-phytotoxic solvent, were appliedin an overall spray to the foliage and surrounding soil of selectedplant species. One day after treatment, plants were observed for rapidburn injury. Approximately fourteen days after treatment, all specieswere visually compared to untreated controls and rated for response totreatment. The rating system was as described previously for Test A. Thedata are presented in Table C.

All plant species were seeded in Woodstown sandy loam soil and grown ina greenhouse. The following species were grown in soil contained inplastic pots (25 cm diameter by 13 cm deep): soybeans, cotton, alfalfa,corn, rice, wheat, sorghum, velvetleaf (Abutilon theophrasti), sesbania(Sesbania exaltata), Sicklepod (Cassia obtusifolia), morningglory(Ipomoea hederacea), jimsonweed (Datura stramonium), cocklebur (Xanthiumpensylvanicum), crabgrass (Digitaria sp.), nutsedge (Cyperus rotundus),barnyardgrass (Echinochloa crusgalli), giant foxtail (Setaria faberii)and wild oats (Avena fatua). The following species were grown in soil ina paper cup (12 cm diameter by 13 cm deep): sunflower, sugar beets, andmustard. All plants were sprayed approximately 14 days after planting.Additional plant species, such as johnsongrass and field bindweed, aresometimes added to this standard test in order to evaluate unusualselectivity.

Again, Compound 1 appeared to be one of the most active compounds whenapplied post-emergence, and the results for this compound are presentedin Table C. All of the compounds tested, however, were shown to behighly active post-emergence herbicides. Some of the compounds, forexample, Compounds 3, 4, 6 and 15, show potential utility for selectivepost-emergence weed control in wheat.

The procedure described as Test D was performed to illustrate thepotential utility of Compound 3 as a post-emergence herbicide in wheatand barley.

Test D

Two ten-inch in diameter plastic pans lined with polyethylene linerswere filled with prepared Fallsington silt loam soil. One pan wasplanted with seeds of wheat (Triticum aestivum), barley (Hordeumvulgare), wild oats (Avena fatua), downy brome (Bromus tectorum),cheatgrass (Bromus secalinus), blackgrass (Alopecurus myosuroides),annual bluegrass (Poa annua), green foxtail (Setaria viridis),quackgrass (Agropyron repens), Italian ryegrass (Lolium multiflorum) andripgut brome (Bromus rigidus). The other pan was planted with seeds ofRussian thistle (Salsola kali), tansy mustard (Descuraina pinnata),smartweed (Polygonum pensylvanicum), tumble mustard (Sisymbriumaltissium) kochia (Kochia scoparia), shephard's purse (Capsellabursa-pastoris), Matricaria inodora, black nightshade (Solanum nigrum),yellow rocket (Barbarea vulgaris), rapeseed (Brassica kaber) and wildbuckwheat (Polygonum convolvulus). The above two pans were treatedpre-emergence. At the same time two pans in which the above plantspecies were growing were treated post-emergence. Plant height at thetime of treatment ranged from 1-15 cm depending on plant species.

The test compound applied was diluted with a non-phytotoxic solvent andsprayed over-the-top of the pans. An untreated control and a solventalone control were included for comparison. The plantings weremaintained in the greenhouse for 19-21 days at which time the treatmentwas compared to the controls and the effects visually rated. Therecorded data are presented in Table D.
